Energy and Fuel

5. The ability to do work or cause change
7. Movement of a substance from one place to another (wind)
8. The law that states that energy cannot be created or destroyed but can be changed from one form to another
9. The energy stored in the bonds of atoms and molecules (for example, in biomass, petroleum, natural gas, propane, coal, and food)
11. A source of energy that can be replenished in a short period of time
13. How much useful energy you can get out of a system (the percent of input you get as output.)
15. Converting from one form of energy to another always involves a _______ of usable energy
17. Cannot be replenished over a short period of time

1. Another energy source must be used to make it (electricity)
2. The movement of energy through substances in longitudinal waves
3. Energy of place or position. (Water behind the dam at a hydropower plant)
4. Energy stored in the nucleus of an atom (that holds the nucleus together)
6. Energy can change form, but the total_____ of energy in the universe remains constant
10. Energy caused by the movement of electrons. (Lightening and electricity)
11. Energy carried by electromagnetic waves (solar energy)
12. (heat!) the internal energy of substances caused by the vibration or motion of their atoms and molecules. (Geothermal)
14. A substance that provides energy as the result of a chemical change (contains stored energy)
16. Mechanical Energy Energy stored in objects by the application of force (compressed springs, stretched rubber bands, etc.)
